例句与用法
- Those factors made our study on daylighting far from the developed countries . some people try to solve the problem , and they did achieve in some aspects
为改善这一状况，我在导师的指导下开始对北京地区的天空亮度和室外水平照度进行观测。 - But those were not enough - cause there are many factors that affect daylight , we cannot grasped the rule of daylight change . so most countries in the world , made the outdoor horizontal illuminance of overcast sky as the daylighting standard
为解决这些问题，各国的学者通过对本国光气候的长期观测得到了晴天天空、阴天天空和中间天空的天空亮度分布，并希望以此为依据，制定各个不同国家和地区的采光标准和天然采光的计算方法。 - This kind of standard wastes too much sunlight energy , so to change the situation , many people began to study the intermediate sky . now , they had drawn some conclusions . in our country , this kind of research did not go for a long time , and we lack of large amount of data
摘要目前，由于对我国的光气候研究时间较短，且缺乏大量、准确的观测数据，无法得到准确而全面的晴天、阴天以及中间天空的天空亮度分布，因而仍以阴天时的室外水平照度作为天然采光的标准。 - But there are still many things need to do . to improve the situation , under the direction of my teacher , i began to observe the zenith luminance of clear sky and overcast sky . and after analyzing the observed data , i drew the zenith luminance in beijing
虽然如此，通过对北京地区晴天和阴天天顶亮度的观测，仍可以得到北京地区晴天和阴天天顶亮度随太阳高度角变化的规律，从而得到天顶亮度值，将其代入cffi标准晴天和阴天天空亮度公式后得到北京地区的晴天和阴天天空亮度绝对值。
